Update: We’re hearing unconfirmed reports that Shane Mosley is at the airport ready to fly back to America.

Sugar Shane Mosley is threatening to pull out of Wednesday’s clash against Anthony Mundine in Sydney, Australia, unless he receives a large percentage of his $1 million purse in advance. According to the The Daily Telegraph, the pre-fight press conference scheduled for today was cancelled and Mosley has boycotted several media commitments. It is far from certain whether Mosley will show up at the Tuesday weigh-in. So far ticket sales have reportedly been slow for the bout at the Sydney Entertainment Centre and Mosley’s team apparently is worried he won’t get paid.
